我正在研究 WEB API。当我尝试使用 ADO.NET 或实体框架插入数据时。它显示错误消息“尝试访问已卸载的应用程序域。（来自 HRESULT 的异常：0x80131014） ”。但相同的代码正在控制台应用程序项目上工作。数据库服务器位于 AWS。代码如下。
SqlConnection con = new SqlConnection(constring);
con.open();
sqlcommand cmd = new sqlcommand();
cmd.Connection = con;
cmd.commandtext = "uspsaveregistration";
cmd.commandtype = commandtype.storedprocedure;
sqlparameter[] sqlp = new sqlparameter[] {
new sqlparameter("@mobile_no",sqldbtype.varchar),
new sqlparameter("@password",sqldbtype.varchar),
new sqlparameter("@first_name",sqldbtype.varchar),
new sqlparameter("@last_name",sqldbtype.varchar),
new sqlparameter("@gender",sqldbtype.varchar),
new sqlparameter("@dob",sqldbtype.varchar),
new sqlparameter("@designation",sqldbtype.varchar),
new sqlparameter("@address",sqldbtype.varchar),
new sqlparameter("@mapid",sqldbtype.int),

};
sqlp[0].value = mobileno;
